' This invention relates to improvements 1n loose lead pencil holders the lead-tube of which is slidable or adjustable within the.

clamping sleeve or head andis automatically charged with a new lead from a receptacle, connected with the lead-tube by a funnelshapedmember and containing a supply of leads.. v

'lheessential feature of 'the present invention consists in that the lead .is clamped by the head of the pencil, and the clamped lead 4isA fed forward by a rotary member or knob. A particular advantage vof the construction according to the present inventionresides in the combination of a pencil with automatic feed with a loose lead pencil holder, in which a large number of leads can be stored.

One mode of carrying out'the present inp vention'is illustrated by way of example on the accompanying sheets of drawings, in

- which--y Figures 1, 2 and 3 show in sectional elevation one embodiment of the invention; igure 4 is a cross-section view, the section being taken on line a--b of Figure 1.

In the embodiment shown in Figs. 1 to 4, the forward endy of the barrel 1 is provided with an inner screw-thread into which is screwed the head or mouth-piece 2 of the loose lead pencil holder, the bore of the same being of particularshape. The top portion of the same is shaped as clamping sleeve 3, while the diameterof the bottom portion of the bore 3b corresponds to the diameter of the lead.

. The lead-tube 4 is slotted at 4a and, within the enlarged cylindric part 3c of the bore 3, is connectedwith the cylindric tube 8 by a conical shaped or funnel-shaped member 7 g The rear end of the tube 8 is provided with a left-handed thread, which is engaged by a corresponding thread of the tube 10, which is reduced in diameter 9 and together with vthe tube -8 forms the lead storage compartment 11. f

Ifit is desired to insert a new lead from the storage compartment into the lead-tube 4c or to' push forward a -lead,.the head or mouth-- piece 2-is slightly screwed out of the barrel 50 1, as shown in Fig. 1, so that the lead-tube 4- and the lead-are not ing action. a new lead subjected to any clamp- Now the lead in the lead-tube or from the storage compartment .11 drops forward. This procedure is shown 1n Fig. 1. Now the head 2 is screwed into the barrel 1, so that the lead-tube 4 is clamped again,

left and, owing to gag ement between the tubes 8 as shown in Fig. 2. Hereafter the handle 18 is turnedto the the screw-threaded enand 10, the tube A 8 as well as the lead-tube 4 and the clamped lead are moved forward solely in an axial direction,

so that the lead projects out of the` head 2. The rotation of the pipe 8 is prevented by the cooperati tions 1, 1n and the 8n.

Loose lead pencil holder comprising in combination a barrel, a lead-tube slotted at one end and arran ged within the same, a

clamping head screwed to the barrel for clamping the lead in the said lead-tube, consisting of two member connecting slotted end of the a lead storage compartment parts, v a funnel-shaped the bottom part of the said compartment with the lead-tube, means for rotating the partment and top part of the said comsecuring the same against axial movement, and means for transforming the Protary motion of the said top part into an' axial movement of the said bottom part.
